Tip
The DC wire gauge to connect the Level Up module to the trailers converter should be at least 22 gauge. The charge current for the Level Up module is limited to 220 mA. The specified wire gauge is based on a 12 volt DC supply, a maximum of 300 mA of current, an a two percent voltage drop margin over 20 feet of wire.
